The device allows to combine signals from Quad LNB and terrestrial TV senders and distribute them to four FM/TV/SAT outlets. At each input the combiner has advanced filter circuits, which results in very good isolation between SAT (LNB) and Terr. TV inputs.

Quad LNB is in fact a complex of four fullband LNBs, encapsulated in one housing. Each of them can be independently controlled. This way the installation is suitable for making use of four autonomous receivers. Adequate installation also makes possible to receive terrestrial TV programs.
